Gardeners who use dung as fertilizer should check to make certain that the animal source has not grazed on picloram-treated hay, as the dung still has broadleaf-killing potency. [ 8 ] In regards to occupational exposures, the U. S. Occupational Safety and Health Administration has established a permissible exposure limit of 15 mg/m 3 total ...
Controlled-release fertilizer is also known as controlled-availability fertilizer, delayed-release fertilizer, metered-release fertilizer, or slow-acting fertilizer. Usually CRF refers to nitrogen-based fertilizers. Slow- and controlled-release involve only 0.15% (562,000 tons) of the fertilizer market (1995).
A 15-ton crop of onions uses up to 19 lb of sulfur and 4 tons of alfalfa uses 15 lb per acre. Sulfur abundance varies with depth. In a sample of soils in Ohio, United States, the sulfur abundance varied with depths, 0–6 inches, 6–12 inches, 12–18 inches, 18–24 inches in the amounts: 1056, 830, 686, 528 lb per acre respectively.

The term "calcium ammonium nitrate" is applied to multiple different, but closely related formulations. One variety of calcium ammonium nitrate is made by adding powdered limestone to ammonium nitrate; [1] [2] another, fully water-soluble version, is a mixture of calcium nitrate and ammonium nitrate, which crystallizes as a hydrated double salt: [3] 5Ca(NO 3) 2 •NH 4 NO 3 •10H 2 O.
The main use of calcium cyanamide is in agriculture as a fertilizer. [3] In contact with water, it hydrolyses into hydrogen cyanamide which decomposes and liberates ammonia: [5] CaCN 2 + 3 H 2 O → 2 NH 3 + CaCO 3. It was used to produce sodium cyanide by fusing with sodium carbonate: CaCN 2 + Na 2 CO 3 + 2 C → 2 NaCN + CaO + 2 CO

Ammonium heptamolybdate is the inorganic compound whose chemical formula is (NH 4) 6 Mo 7 O 24, normally encountered as the tetrahydrate.A dihydrate is also known. It is a colorless solid, often referred to as ammonium paramolybdate or simply as ammonium molybdate, although "ammonium molybdate" can also refer to ammonium orthomolybdate, (NH 4) 2 MoO 4, and several other compounds.
Residue limits evaporation, conserving water. Evaporation from tilling increases the amount of water by around 1/3 to 3/4 inches (0.85 to 1.9 cm) per pass. [66] Gully formation can cause soil erosion in some crops, such as soybeans with no-tillage, although models of other crops under no-tillage show less erosion than conventional tillage.
